I am sorry, I hadn't realised being a teenager made me [FONT='Verdana','sans-serif']ineligible [/FONT]to ask questions of a technical nature.
I simply happen to be quite interested in many of the technical aspects of aircraft - that is in fact one of the reasons I look forward to becoming a pilot (don't suggest that I become an aircraft engineer, I've looked into that already).
I thought that such a possibility might be unusual if not unheard of, but that doesn't mean to say that I should not be allowed to ask.
I would also be interested in knowing how you appear to have gained the knowledge of my age, seeing as my personal profile options show it as being "hidden".
